To allwhomitmayconce'mlw V Be it known I that I, FC AR LES ,PAEs PLOW, a citizenof the United: States, residing at- Bufial0,- in the county of Erie and State of New York; have; invented a new=and useful Improvement in Apparatus for, Use in Making elts. or the like,'of.; w hich: the followingis a s ecificationr' ri T i This invent on relates to improvements in apparatus for use in connection with the vuls canizing' of'belting of theykindcommonly referredto as rubbergbelting. ,Apparattus of this-. kin"d. generally includes a pair of heated-- platens which are -adap'ted- ;1t0; be

a belt; for the purpose ofeuring ortvulcan'iz or members adapted to,ieonfiuethe-sides of the belts, to hold the same against spreading. In the use of an apparatus .or'press of this kind a length ofbelt to becu'red is firstfed'to the apparatus by pulling the sameflejngthwise into. the desired positions a ndr-flis then stretched, Whiehcausesfithe portionof the kind in other respects hereinafter;speeified.-

Each ofthe side bars C is connected intervals with laterally extending bars or links rev D by means of whichthe side bars are moved,

laterally of the apparatus. In the particular construction-shown; each of these connecting links D is provided with a rounded end or head portion at which is" adapted-"tot fit into a correspondingly shaped aperture or recess in theouter edge of theside bar; The end or head portion d may besubstan tially in alinement witlrthe connecting link D or may extend laterally therefrom as indicated at d inorder that the pressure of the'l'inks acting against the side bars maybe equal distances along theside "bars; 1 a 1 -""In'-'or de'rtoinovethe connecting links-laterally of the apparatus the following mecha-- nism is preferably employed; At each side ofthe apparatusashaftE is arranged which extends substantially throughout the length of the ap ar tus-and which is suitably jour= naledon brackets F which are preferably secured "to 'the' side of the lower platen, the brackets shown'being secured to the side walls by means -of" bolts or machine screws f.

Each'-"oftheshafts is provided with a plurality of ecceritricsje secured at intervals to the-=shaft and'cooperating with eccentric straps G.-' l

mannerffo'r example the eccentric straps in the-"construction"shown are provided with extensionsg'which are pivotally' connected with the slides H. "Asshown in the drawings,'the"shdes Hare provided-"with slots 7:

into the extensions g of the eccentrics enter, and "pivot pins'h secured on the slides and extending through the slots 'h form connections between the eccentric straps and the slides: a; 4' Theiupperface ofeach slide His preferably; arranged in substantially thesame plane" as the upper face of the lower platen and 'providedwith suitable means for connecting with a link Df'the connection being preferably such'as to permit the connecting linksto be; adjusted with reference to the slides so that 'theside -bar may beheld in different relations to the platens for adapting'theapparatus td operate on belts .of different widths. In the particular construction shown in the drawings this is accqm ranged onaside; of

plished by providing each slide H with an upwardly extending pin or projectiond and by providing eachconneoting link D'wit-h a plurality of holes i into any of which the ,p-inrorprojertionsl may enter, the holes '5 being so spaced on the connecting links as to hold til1B-1Sld9 barsiin such relations as are desirable to operate on belts of different WlCltl1S.= S r": l'm'i The relation between the eccentrics and the slides is preferably suclrthat a half turn of the shafts will cause the slides to move the desired distance. I Anysuitablefinieans may be'provided for turning the=sl1afts,'such forexample as levers K, Figs. 1 and 3, mounted on the-shafts. The shafts arepreferably turned so that when the side bars 0 are in their inner or beltengaging ositions, the eccentrics: will be in, dead center pOsitionsas shown in Fig; 8,so* tha-t pressureon thesidebars W-ill not tendto cause the shaft E to=turn',-thus ensuring a' secure holding of i the side barsinthe desired positions. The side bars G may be held a-gain'st movement in the'direction of their-length by any suit able means; such as rollers-*0 arranged at the ends of the side bars and engaging an end of the lower-platen. I i he'mecha'nism described for moving the side bars is simple and: inexpensive in con struction 'and thoroughly-reliable in opera'-. tiong'a-nd' has the advantage that it can be easily applied to vulcanizing pressesnowin use. Bymeans of the' const-ruction described the' mechanism" can be' very easily adjusted to enablethe apparatus to operate onbelts of different widths.
